Senior School

As with our Primary years, a broad, balanced curriculum remains central to the Secondary experience. Students will continue to explore the themes outlined earlier, ensuring their curiosity is sustained and the excitement of coming to school is nurtured.

World-class courses

We will stretch our students’ academic experience using the externally validated International General Certificates of Secondary Education (IGCSEs) from Cambridge Assessment International. These world-class courses will ensure students have the very best grounding in up to seven subjects, providing a solid platform for the IB Diploma Programme that follows. Alongside their Cambridge IGCSEs, students will maintain a healthy balance of enriching activities, so that they retain their sense of wonder and excitement.

Our oldest students will extend themselves in the International Baccalaureate Diploma Programme, where they will study six subjects which will include one from each of the following areas:

Studies in Language and Literature
Science
Language Acquisition
Mathematics
Individuals and Societies
The Arts

Students will also develop their skills in the three core components of the IB Diploma Programme:

EXTENDED ESSAY

An independent, self-directed piece of research, finishing with a 4,000-word paper.

THEORY OF KNOWLEDGE

Asking students to reflect on the nature of knowledge, and on how we know what we claim to know. It is assessed through an oral presentation and a 1,600-word essay.

CREATIVITY, ACTION & SERVICE

The three strands of Creativity, Action & Service (CAS), often interwoven with particular activities, are characterised as follows:

Creativity: Arts and other experiences that involve creative thinking.
Activity: Physical exertion contributing to a healthy lifestyle, complementing academic work elsewhere in the Diploma Programme.
Service: An unpaid and voluntary exchange that has a learning benefit for the student.
